Good save triggers: the user states a preference, goal, or constraint; completes or abandons something meaningful; a conversation ends. Saving identical content twice is a no-op (`deduped: true`). ## OpenAPI ````yaml /api/openapi.yaml post /api/v1/memories openapi: 3.1.0 info: title: Conare API version: 1.2.0 summary: Per-end-user memory for AI applications. description: > The Conare API gives your application a persistent, personalized memory layer. Production applications authenticate as an organization-owned Integration. Every request names an `endUserId`, and that end user's memory lives in its own isolated ConareDB namespace. The physical tenant is an opaque HMAC derived from the Integration and end-user ID; clients cannot select namespaces or address another tenant. On top of storage the API provides hybrid retrieval (vector + BM25, fused and reranked, sub-second), LLM-synthesized **deep recall**, and **proactive suggestions** grounded in a user's memory. Authentication uses a scoped server-side Integration Bearer key (`cint_...`). The secret is shown once and persisted by Conare only as a SHA-256 digest. Keep it in a server-side secret manager; never ship it to the browser. Legacy personal `cmem_...` keys remain accepted during migration. Every response includes `X-Request-Id`. Send a caller-generated safe value (1–128 characters; first alphanumeric, then `A-Za-z0-9._:-`) to correlate one request through the Conare edge and memory plane; otherwise Conare generates one. Errors use a stable `{ statusCode, code, message, requestId, details? }` envelope and never include internal tenant IDs or backend error text. contact: name: Conare url: https://conare.ai email: artem@conare.ai servers: - url: https://api.conare.ai description: Production (dedicated partner-API host) - url: https://conare.ai description: Production (alias — same API, on the main host) security: - bearerAuth: [] tags: - name: Integration description: Credential, configuration, and backend readiness. - name: Memories description: Write and search a single end user's memory. - name: Recall description: LLM-synthesized personalization primitives. - name: Embeddings description: Embed text with Conare's own retrieval embedding model. - name: Connectors description: >- Let end users connect any of ~200 data sources that flow into their memory. - name: Users description: End-user lifecycle (GDPR). paths: /api/v1/memories: post: tags: - Memories summary: Save a memory description: | Save one distilled observation — a sentence or a paragraph, not raw event logs — to the end user's memory.
